Donating Blood. Who Can Donate? Anyone who is in good health, is at least 18 years old (persons 16 or 17 years old may donate with a Blood Program permission slip signed by a parent or guardian), and weighs at least 114 pounds may donate blood every 56 days.
Donors must be at least 17-years-old to donate. However, some states allow 16-year-olds to donate blood with parental consent. A parent will need to review the Student's Guide to Blood Donation (also available in Spanish) and sign the parent/guardian consent form for the young adult to be able to donate blood.
